Answer:

2/3

Step-by-step explanation:

A = rolling a six

B = rolling a number less than 4

Probability of A or B

P(A) or P(B) = P(A) + P(B) - P(AnB)

Probability = (number of required outcome / Total possible outcomes)

P(A) = 1 / 6

P(B) :

Required outcomes = (3, 2, 1) = 3

P(B) = 3/6 = 1/2

P(AnB) = A={6} ; B = {1,2,3} ; AnB = {}

P(AnB) = 0

Hence,

P(A) or P(B) = 1/6 + 1/2 - 0

= (1 + 3) / 6

= 4/ 6

= 2/3

Step-by-step explanation:

The length of the longest piece will be 15 ft.

We have a 48 ft rope is cut into 5 pieces according to the ratio →

2 : 2 : 3 : 4 : 5.

We have to determine the length in feet of the longest piece.

Now -

2x + 5x = y

x = [tex]$\frac{y}{7}[/tex]

Smallest piece is of length → 2x → [tex]$\frac{2y}{7}[/tex]

According to the question, we have -

Length of rope = 48 ft

Ratio in which they are cut = 2 : 2 : 3 : 4 : 5.

Therefore -

2x + 2x + 3x + 4x + 5x = 48

16x = 48

x = 3

Length of the longest piece = 5x =  5 x 3 = 15ft

Hence, the length of the longest piece will be 15 ft.

Answer:

y = x + 4

y = -2x - 4

Step-by-step explanation:

Since equation of the line having slope 'm' and y-intercept 'b' is given by,

y = mx + b

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of line passing through (1, 5) and (-1, 3),

m = [tex]\frac{5-3}{1+1}[/tex] = 1

y-intercept 'b' = 4

Therefore, equation of the line is,

y = 1.x + 4

y = x + 4

Now slope of another line passing through (-4, 4) and (-1, -2) will be,

m = [tex]\frac{4+2}{-4+1}[/tex]

m = -2

y-intercept 'b' of this line = -4

Equation of the other line,

y = (-2)x - 4

y = -2x - 4

Therefore, system of equations is,

y = x + 4

y = -2x - 4

The system of equations is given by: y = x + 4 and y = -2x - 4

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the rate of change and b is the y intercept.

The first line passes through point (-1, 3) and (1, 5) hence:

[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3=\frac{5-3}{1-(-1)} (x-(-1))\\\\y=x+4[/tex]

The second line passes through point (-4, 4) and (-1, -2) hence:

[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-4=\frac{-2-4}{-1-(-4)} (x-(-4))\\\\y=-2x-4[/tex]

The system of equations is given by: y = x + 4 and y = -2x - 4

Answer: C

Step-by-step explanation:

We know that a relation is any set of ordered pairs, but a function is when there is only one y value for x value.

So, basically, if a graph is a function, it is a relation as well.

Let’s check if this is a function.

We can use the vertical line test- if we draw a vertical line through any point on the graph and it only intersects one point, it is a function

In our case, it passes the vertical line test.

Therefore, it is both a function and a relation, which corresponds to letter C.

Your statement is a little ambiguous due to type mistake, so I am assuming you meant to say:

'if 12 fl. oz. bottles cost $84 how much does one bottle cost? Find the Unit Rate.

so I am solving based on '12 fl. oz.' bottles costing $84.

Answer:

unit rate = 7 $ per fl. oz.

Therefore, the 7 $ per fl. oz is the unit rate.

Step-by-step explanation:

We know that a unit rate is basically a fraction (also called ratio) between two different units with a denominator of 1.

For example, kilometers per hour, and heartbeats per minute, etc.

Here, I assume, by 'unit rate' means you mean to say 'cost per fl. oz.'

Given

The cost of 12 fl. oz. bottlers = cost $84

The cost of 1 bottle cost = $84 ÷ 12 oz = 7 $ per fl. oz.

Hence,

unit rate = 7 $ per fl. oz.

Therefore, the 7 $ per fl. oz is the unit rate.

The divorces occur when two person fails to accept each other as a life partner. In the country the divorce rate is about 7% of which mostly couples are at the age of 20 - 25. The people of age 30 plus are less likely to get divorced as they have matured mind sets which accepts each other differences and tries to adjust the situation.

Divorce describes a form of marital separation which is usually undertaken by a court. It occurs when one or both partners decide to quit being married.

The causes of rising divorce rates among middle - aged may include :

Rising cases of infidelity as spouses continue to find it difficult to be committed in marrige. Sacrifices which helps foster lasting partnership can no longer be undertaken.

Also, the need to be independent as taken over at this time, as partners begin to see marriage as a bond age which prevents or curtails them from what they would love to indulge in.

Lastly, some now see divorce as norm due to the social influence it has transmitted across to various individuals. Now, so many choose to divorce at any minor challenge marriage brings.

Angle Measurement Units

To convert from different units for angle measurements, we have to recall that:

180 degrees = π radians

If we are given the angle in degrees, multiply by π/180 to convert it to radians.

If the angle is given in radians, multiply by 180/π to convert to degrees.

We are given the angle:

[tex]\displaystyle x=\frac{15}{16}\pi[/tex]

Multiplying by 180/π:

[tex]\displaystyle x=\frac{15}{16}\pi\cdot \frac{180}{\pi}[/tex]

Simplifying:

[tex]\displaystyle x=\frac{15*180}{16}[/tex]
